Application filed m 31, 1e24, Serial No.

In maneuvering with fluid gearings and fluidcouplings it is of great importance to drain the chambers and passages of the fluid circuits rapidly and entirely. For the purpose of draining sai'd chambers and passages it has been the practice, hitherto, of arranging at the circumference of 'thechambersa number of aperture's, that were kept. open or closed by means of valves. With, the. valves open, the fluid was thrown out by.

' ture in a manner at once simple and effective and consists in opening andclosing the draining apertures at the circumference of the chambers by displacing a ring in a tangential and axial direction. Such ring is provided, at the outer circumference, with guide railsin which blocks or rolls engage, which are a'rran ed at the gearcasing. At the inner circum erence the ring is provided with a slot in which blocks or rollsmove, which are fitted to'the drain slide valves.

In the drawing accompanying the specification and forming part thereof, a. preferred modification embodying the principle of the inventionhas been re resentedas an example. In said drawin igC l is a sec tion through the draining evice on line 6-1; of Fig. 2; Fig. 2 is a cross section on' line a'-a of Fi 1, andFig. 3' is a detail view seen in the irection of the arrow-y in Fig. 2.

In the drawing Figures 1 to 3' disclose a draining device according to the presentinvention as arranged on two contiguous circuit chambers. 'K and'K -denote the two chambers; 1 is the fixed casing, 2 the secondary rotor, 3 and 3" the primary rotors; 4 denotesa'spurwheel with a shaft and a bowl wheel;. 5 the drivin ring, 6 are the valve motion rolls, 7 the grain slide valves, 8 the supporting rollers, 9 the guide rollers for the driving ring, 10 the guide rails on the driving ring, 11 the drain holes of the cham- 729,421,1114111 Germany January 8, 1924.

her K 12 the drain holes of the chamber K 13 the slot ofthe driving ring.

- The draining device. is represented with the drain holes 11 closed by means of the slide valves 7, the drain holes 12 being'open, however. therefore thrown into gear, K being drained empty,'however, and therefore, thrown out of gear. If thespur wheel 4 engaging the toothed portion of the driving ring 5' is turned, the driving ring 5 will also turn, be

ing supported on the rollers 8. Fitted to the outer circumference of the driving ring 5 are several oblique guide rails 10, which slide The chamber K is filled and is along the rolls, 9 fixed to the casing. When the driving ring 5 is turned, the guide rails slide along the rollers 9, and,.in consequence of the oblique position of the guide rails,the

driving ring 5 is displaced axially in one or the other sense according to the direction in 1 which the driving rin driving ring 5 an annufar slot 13 is provided running entirely around the driving ring.

Into this slot 13 enter the rollers 6 arranged at' the slide valve 7 ("These slide valves 7 are carried along when the adjusting, or driving ring 5 is displaced radially and axially by means of the toothed segment. The draining slide valves 7 are bored hollow and are fitted with different overlappings. According to how these laps are adjusted -both ircuits may be opened or one or the othe cycles may be closed. The rollers 8 are positioned parallel to the guide rails 10 and corresponding to the direction in which the driving ring is being turned.
